I was thinking...
*Antanias dangles a ball of yarn in front of me to stop this thread. No pun intended.*
IF there are multiple jobs per class, that perhaps there would be a Conjurer that does specialize in Wind and Earth magick. With spells such as Aeroga and Stonega. Which may only leave room for three more abilities for them.
And I think I'll make a separate thread for the other thing I was thinking.
